i Letters PatentNo. 95,003, dated September 21, 1869;

IMPRovED EXTENSION-TABLE."

The Schedule referred to invthese Letters Patent and making parl: of the same.

To all whom 'it-may concern: i

Be it* known that I, J OSEPH P. CURRY, of Vineennes, in the county of Knox, and State of Indiana,

vhave invented a new and `useful Improvement in Extension-Tables; and I do hereby declare that the-fol` -nient in extension-tables, whereby they are made more r convenient arid useful lthan they have heretofore been;

and consists in extending and contracting the table by means of la shaft, crank, and cords, as will be hereinafter ,more fully described.,

, In the accompanying drawing- Figure l represents Ia plan view of the table, with the top orV cover off, showing the table partially extended, and the method of operating the parts.

Figure 2 is a vertical cross-section, "through the line a :z: of fig. 1, with the top on.

Similar letters of reference indicate corresponding parts. l

The arrangement of `the sliding' rails or runninggear of this table'do not differ materially from those of ordinary extension-tables, but, in addition to being grooved and tongued, they `are grooved for cords on each side,V the cords being arranged for extending the table, while, by vanother central cord, the table is con; tracted. 1

These cords are operated by means of the transverse shaft A,'which is revolved bythe crank B.

O O are the side cords for extending the table, and D'is`the central cord, by which the table is contracted. 4 l I 0n tile-shaft A there may be a drum, E, to which 4 the cords are so attached, that when the cords C C wind' up around ythe drum in extending the table, the cord Dunwinds, and cioe eerste x The .extension-cords O C, being attached to the drinn E, (orto the shaft direct, whidh may be used without a drnm,) are carried around a series of pulleys, f, as indicated by the arrows. p i The rails G H are fast to the opposite ends of the table. The rail I slides between them.

The cord C passes from the shaft around the end of G,.and around the end of I, as seen at J, from thence throughthe rail I, as indicated Yin dotted lilies at 7:; and 'around the other end of I, and to the end of H, wherev it is fastened.

The shaft A being supported on suitable journalboxes at one end of the table, as ,represented in the drawing, it will be seen that when the shaft is revolved, so as to wind up the cords C, the effect will he in the lirst place to draw the stop L to the stop L',

`and the motion of the shaft being continued, the stop m will be drawn to the stop onf, whenthe lnovelnent will cease, as the table will then`4 be extended.

`While the table has been thus moving, and the cords O C winding up', the cord l) has been unwind- 111g.

This lcord D is attached to the shaft or drum at one end, and to the end of the table, as seen at n, at the other end..

`New, if the motion of the shaft is reversed, the cord D will be wound around the drum-or shaft, while the cords C will be unwound, and the parts or endsof the` table will be drawn together.

It will be seen that bysimply turning the crank, the table is extended or contracted, as may be desired.

Having thus` described my invention,

What I claim as new, and desire to secure by Letters Patent, is-. ,Y

The combination of the slide G H with the cords C O and D, and shaft A, substantially as and for the purpose specified. v

The above speciicationof my invention signed by me, this 30th day of July, 1869.
